But I do hope they support third party drives, Apple's SSDs are way overpriced and often much slower.
Toshiba's SSDs run at 200 MB/s+, which is about the maximum a SATA 3GB/s SSD can do. For anything faster they'd need to upgrade to non-Toshiba SSDs, more specifically SSDs which support SATA III's 6GB/s Bandwidth. So far we've still been stuck with SATA II on Macs. Maybe this year finally.....
Apple's current SSD's are not overpriced, and they're pretty fast.
Uh, not really. SATA III SSDs can reach 400+MB/s Read/Write already, for example the Corsair Peformance 3 Series, while Apple's bound themselves to SATA II SSDs, which are bottlenecked into 200 MB/s performance.
Also, seeing as the Performance Degradation that has already happened cannot be 100% reverted even with future TRIM Support, they're technically a bit overpriced. If I bought a 2010 iMac on release, by now my SSD would be functioning at say around 70 MB/s due to the constant writing and deleting. Even if I got TRIM tomorrow with 10.6.7, I wouldn't get 100% of my Drive's performance back. For what we pay for them, for not even having TRIM, they're overpriced. That money is best spent on an OWC Drive which at least uses SandForce Controllers which have built-in "Intelligent Garbage Collection." Or some other Manufacturer's Drive with Garbage Collection or SandForce Controllers.
But, if you buy a drive with a Sandforce, or similar controller, trim support is much less of an issue.
True. Although, SandForce has been proven to not always manage to do as good as job as TRIM. SandForce + TRIM together are the ultimate force for stopping SSD Performance Degrading though, so summarized:
SandForce and TRIM are both excellent, but together they're better than either of the two apart.
What I'm curious about is when this will be backported to the MBA, given that 100% of them are SSD-based
Seeing as this is on the custom 10.6.6 Build in the MacBook Pro 2011s, all Macs should have the TRIM feature in 10.6.7, once the MacBook Pros and the rest of the Macs are merged into one "Universal Build."
TRIM should be implemented by the drive manufacturers, in hardware. It shouldn't be something the OS needs to worry about.
Implementing it on a Hardware Level means nothing. I can buy an OCZ Vertex 2 SSD which has TRIM, but it wouldn't matter, because OS X doesn't support TRIM. You need both the Drive and
the OS to support TRIM for it to work. To have it only necessary on a Hardware Level to work, you'd need some sort of TRIM Controller, like the SandForce Controllers some SSDs come with which have their own "Intelligent Garbage Collection."
For Apple picked SSD's, or for any SSD?
I plan to wait and see what Apple supports in the way of TRIM on 3rd party SSDs. If they don't, I'll buy a Macbook with a BTO SSD. Anyone know if the new MacBooks are SATA 6.0 GB?
So far this TRIM support is bound to Apple-selected SSDs. Also, no. Apple is still on SATA II, 3GB/s Bandwidth. Maybe with this year's Desktop re-fresh we'll see them starting to move onto SATA III.
Also, for anyone that wants to RAID 0 SSDs: You can RAID 0 SandForce Controllers, so you should be able to RAID 0 SSD Drives with SandForce Controllers. OCZ's RevoDrive X2 has SandForce Controllers set to RAID 0.
Maybe they're mad that you're violating your NDA or using software that doesn't belong to you.
You do realize barely anyone is even aware that its under NDA? Besides, Apple isn't even bothering to contain the information. If they cared, they'd have slapped AppleInsider and all the other Sites with "Cease and Desist" orders by now for all the Lion Developer Preview Content they posted on.
